The Spanish side‚Äôs playing, training and youth team kits will be manufactured by Adidas, in a deal first reported in December. The contract came into effect on 1st July and Real‚Äôs players have already begun training in Adidas-branded gear.

Adidas previously supplied the San Sebasti√°n-based side‚Äôs kits during the 1970s and 1980s, and replaces current technical partner Nike. No financial terms were released.

Real Sociedad‚Äôs president, Jokin Aperribay, said: ‚ÄúThis is really magnificent news. We are happy because Real Sociedad has been able to attract such a globally-acclaimed and revered brand as Adidas.

"For us this represents a new impetus ‚Äď in this particular case, a commercial impulse in our objective to cement Real Sociedad‚Äôs presence in Europe. This is the start of an alliance which I am sure will bring much happiness.‚ÄĚ
